    Hi folks wasn't to sure where to put this just purchased an Ibiza fr tdi 6l and the mpg gauge miles left in tank and trip computer appear to be very wrong.

    RPM and speedo appear to be correct,

    I filled car up yestardy and was expecting it to say something like 500miles left instead it said 250miles left I covered a almost what I believe to be 100miles before needle moved and it still said 250miles left and trip said I had only done 40miles.

    Mpg gauge hasn't went above 30mpg average is 27mpg I know this isn't right also.

    Has anyone ever come across this before and know how to fix it is it just a case of getting a new dash?
